Medical Disclaimer

The calculators and information on FitFuelTools are provided for educational and informational purposes only and are not intended as medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional before making health, nutrition, or fitness decisions.

2. Description of Service

FitFuel Tools provides free, browser-based health and nutrition calculators including BMI, calorie, macro, TDEE, protein, body fat, ideal weight, water intake, sleep cycle, and age calculators. All calculations are performed locally in your browser. We do not store any health data you input.

3. Medical Disclaimer

Our calculators use standardised scientific formulas (such as the Mifflin-St Jeor equation and the US Navy body fat method). These produce estimates based on population-level data and may not be accurate for all individuals. Results are influenced by factors our calculators cannot account for, including medical conditions, medications, genetics, and individual metabolic variation.

Always consult a qualified healthcare professional — such as a doctor, registered dietitian, or certified fitness professional — before making decisions about your diet, exercise, health, or medical treatment. Do not disregard professional medical advice or delay seeking it because of something you have read or calculated on this Site.

If you are experiencing a medical emergency, call your local emergency services immediately.
